• Ensure architectural consistency, traceability, and alignment with Government-approved objectives, standards, and governance processes.
• Lead architectural decision-support activities, including evaluation of tradeoffs, risks, and alternatives.
• Coordinate across Government stakeholders, integration partners, engineering teams, and cross-functional groups to ensure cohesive architectural design.
• Ensure proposed technical solutions adhere to enterprise architecture standards, security requirements, and governance controls.
